Carnation plant named ‘Hilbechapell’

ABSTRACT

A new and distinct cultivar of Carnation plant named ‘Hilbechapell’, characterized by its compact, upright to broadly spreading and uniformly mounding plant habit; freely branching habit; freely flowering habit; relatively large yellow green-colored double flowers; and good container and garden performance.

Botanical designation: Dianthus L.

Cultivar denomination: ‘HILBECHAPELL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus L., grown commercially as a container plant and hereinafter referred to by the name ‘Hilbechapell’.

The new Carnation plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new container Carnation plants with numerous attractive flowers.

The new Carnation plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in May, 2012 of Dianthus L. ‘Mel’, not patented, as the female, or seed, parent with a proprietary selection of Dianthus L. identified as code number 1306, not patented, as the male, or pollen, parent. The new Carnation plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in June, 2013.

Asexual reproduction of the new Carnation plant by terminal cuttings propagated in a controlled greenhouse environment in De Kwakel, The Netherlands since March, 2014 has shown that the unique features of this new Carnation plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Carnation have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hilbechapell’. These characteristics in combination distinguish ‘Hilbechapell’ as a new and distinct Carnation plant:

-   -   1. Compact, upright to broadly spreading and uniformly mounding         plant habit.     -   2. Freely branching habit.     -   3. Freely flowering habit.     -   4. Relatively large yellow green-colored double flowers.     -   5. Good container and garden performance.

Plants of the new Carnation differ primarily from plants of the female parent, ‘Mel’, in the following characteristics:

-   -   1. Plants of the new Carnation grow faster than plants of ‘Mel’.     -   2. Flowers of plants of the new Carnation have more petaloids         than flowers of plants of ‘Mel’.     -   3. Flower petals of plants of the new Carnation are not as         deeply incised as flower petals of plants of ‘Mel’.     -   4. Flowers of plants of the new Carnation are yellow green in         color whereas flowers of plants of ‘Mel’ are yellow and pink in         color.

Plants of the new Carnation differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Carnation are more compact and grow slower         than plants of the male parent selection.     -   2. Plants of the new Carnation have larger flowers than plants         of the male parent selection.     -   3. Flowers of plants of the new Carnation are yellow green in         color whereas flowers of plants of the male parent selection are         dark red in color.

Plants of the new Carnation also can be compared to plants of Dianthus caryophyllus ‘Mel Orange’, not patented. In side-by-side comparisons, plants of the new Carnation differ primarily from plants of ‘Mel Orange’ in the following characteristics:

-   -   1. Plants of the new Carnation grow faster than plants of ‘Mel         Orange’.     -   2. Flowers of plants of the new Carnation have more petaloids         than flowers of plants of ‘Mel Orange’.     -   3. Flower petals of plants of the new Carnation are not as         deeply incised as flower petals of plants of ‘Mel Orange’.     -   4. Flowers of plants of the new Carnation are yellow green in         color whereas flowers of plants of ‘Mel Orange’ are orange in         color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Carnation plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Carnation plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Hilbechapell’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the spring in 11.5-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial container Carnation production. During the production of the plants, day temperatures ranged from 16° C. to 20° C. and night temperatures ranged from 16° C. to 18° C. Plants used for the photograph and description were 13 weeks from planting and were pinched one time at the time of planting. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
